google.appengine.datastore.datastore_query.ResultsIterator

An iterator over the results from Batches obtained from a Batcher.

Inherits From: expected_type

google.appengine.datastore.datastore_query.ResultsIterator(
    batcher
)

ResultsIterator implements Python's iterator protocol, so results can be accessed with the for-statement:

it = ResultsIterator(Query(kind='Person').run()) for person in it: print 'Hi, %s!' % person['name']

At any time ResultsIterator.cursor() can be used to grab the Cursor that points just after the last result returned by the iterator.
